Possible bug in postgres || libpq

Hi

I'm started to try to use postgres as a backend for an bussiness
application run up to what i think could be a bug in either postgres or
libpq

Mainly a

NOTICE: Buffer Leak: [012] (freeNext=-3, freePrev=-3, relname=dsrbk,
blockNum=0, flags=0x4, refcount=64 3)

or similar following a COMMIT and a core after some time.

It is reproducable when running the same commands thrue the psql util.

Log included, i know it isn't pretty sql code but it should work right?
All cursors are on unique indexes.

Iff this is a mailing list of some sort pls cc any answer to my e-mail
address.

Thank's
